Brief Summary:
This is a pivotal Phase II randomised, multi-centre, open-label study to evaluate the efficacy and safety of MB-CART2019.1 compared to standard of care therapy in participants with relapsed/refractory diffuse large B-cell lymphoma, who are not eligible for high-dose chemotherapy and autologous stem cell transplantation.

Condition or disease Intervention/treatment Phase
Diffuse Large B-cell Lymphoma Genetic: MB-CART2019.1 Drug: R-GemOx or BR plus polatuzumab vedotin Phase 2

Detailed Description:

This study should determine superiority of MB-CART2019.1 treatment compared to SoC therapy with R-GemOx (rituximab, gemcitabine and oxaliplatin) with respect to progression-free survival in second-line therapy in participants with R-R DLBCL, who are non-eligible for high-dose chemotherapy and autologous stem cell transplantation.

MB-CART2019.1 is designed to effectively target malignant B cells in patients suffering from late stage haematological B-cell malignancies. MB-CART2019.1 consists of autologous cluster of differentiation CD20/CD19 chimeric antigen receptor (CAR) transduced CD4/CD8 enriched T cells, derived from a leukapheresis and processed by using the CliniMACS Prodigy®. Patients who are suitable for this study will be randomized 1:1 to either MB-CART2019.1 or SoC. Both treatment arms are unblinded.

MB-CART2019.1 arm: Single infusion of fresh formulation of 2.5 × 10^6 CAR-transduced autologous T cells. IMP is only to be administered after a lymphodepleting chemotherapy with fludarabine and cyclophosphamide. For MB-CART2019.1 production, patients will undergo a leukapheresis.

SoC arm: R-GemOx (8 cycles of 14 days each) or (10% of SoC arm) BR (Bendamustine/Rituximab) + polatuzumab vedotin (6 cycles of 21 days each).

The duration of the active part of the study for each individual participant from screening to the end of the 1-year follow-up after infusion of MB-CART2019.1 cells (experimental arm) or the start of SoC therapy (comparator arm) will be approximately 55 weeks. The LTFU in Year 2 after infusion of MB-CART2019.1 cells or the start of treatment in the comparator arm will not be part of the active part of the clinical study and will be reported separately.

    • High-grade BCL, NOS.
    • Primary (thymic) large mediastinal BCL.
    • Disease transformed from an earlier diagnosis of low-grade lymphoma (e.g. an indolent pathology such as follicular lymphoma, marginal zone lymphoma) into DLBCL with DLBCL disease progression subsequent to DLBCL directed systemic treatment.
  2. Relapsed or refractory disease after first-line chemoimmunotherapy:

    • Refractory disease is defined as no CR to first-line therapy,

      • PD as best response after at least 4 full cycles of R-CHOP (rituximab, cyclophosphamide, hydroxydaunorubicin, oncovin and prednisone) cycles as first-line therapy.
      • Stable disease (SD) after 6 R-CHOP cycles as first-line therapy.
      • PR as best response after at least 6 R-CHOP cycles and biopsy-proven disease progression (except where prohibited due to comorbidities) within ≤ 12 months from the completion of the first-line therapy.
    • Relapsed disease defined as complete remission to a first-line therapy followed by biopsy-proven disease progression (except where prohibited due to comorbidities) within ≤ 12 months from the completion of the first-line therapy.
  3. Participant must have received adequate first-line therapy containing at least the combination of an anthracycline-based regimen and rituximab (anti-CD20 monoclonal antibody). Local therapies (e.g. radiotherapies) will not be considered as line of therapy if performed during the same line of treatment.
  4. Archival paraffin-embedded tumour tissue acquired ≤ 3 years prior to screening for central pathology review to confirm DLBCL diagnosis and for analysis of CD20/CD19 expression must be made available for participation in this study. If archival paraffin-embedded tumour tissue is not available, fresh tumour tissue sample (preferred) or core-needle biopsy for this protocol must be made available.
  5. Participants deemed ineligible to receive HDC followed by ASCT based on the treating physician's assessment and meeting the following criteria:

    • Age ≥ 18 years and

      • Prior ASCT (as first-line consolidation) or
      • Haematopoietic Cell Transplantation-specific Comorbidity Index (HCT-CI) > 3.
    • Age ≥ 65 years and 1 of the criteria below:

      • Prior ASCT (as first-line consolidation), or
      • Comorbidities as assessed by an HCT-CI score > 3, or
      • Impaired cardiac function (left ventricular ejection fraction (LVEF) < 50%), or
      • Impaired renal function (creatinine clearance [CrCl] < 60 mL/min) as determined by MDRD (Modification of Diet in Renal Disease) formula or
      • Impaired pulmonary function (diffusing capacity for carbon monoxide or forced expiratory volume in 1 second of 66% to 80%) or dyspnoea on slight activity, or
      • Eastern Cooperative Oncology Group (ECOG) performance status > 1. Documentation of the reason for ineligibility for ASCT must be present in the participant's source data.

    In addition, all participants must fulfil the following criteria:

  6. Age ≥18 years.
  7. Measurable disease according to Lugano criteria. The lesion must be positive on a positron emission tomography scan.
  8. Estimated life expectancy of > 3 months for other reasons than the primary disease.
  9. Woman of childbearing potential (WOCBP) must agree to use highly effective contraceptive measures (Pearl index < 1) or practice true sexual abstinence from any heterosexual intercourse (True abstinence is only acceptable if it is in line with the preferred and usual life style of the participant.) or must have a vasectomised partner as the sole sexual partner (The vasectomised partner must have received medical assessment of the surgical success.) for at least 1 month before the study start, during the study and in the 12 months following the last dose of study treatment. A woman is considered a WOCBP, i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Highly effective methods of contraception include hormonal contraceptives (oral, intravaginal, transdermal, injectable, implantable) and intrauterine devices or systems (e.g. hormonal and non-hormonal) and bilateral tubal occlusion. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A post-menopausal state is defined as no menses for 12 months without an alternative medical cause. WOBC must refrain from egg donation throughout the study until 12 months after the last dose of study treatment.

    Men must agree to use 2 acceptable methods for contraception (e.g. spermicide and condom) or practice true sexual abstinence from any heterosexual intercourse (True abstinence is only acceptable if it is in line with the preferred and usual life style of the participant.), unless they are surgically sterile (meaning at least 2 consecutive analyses following vasectomy demonstrate absence of sperms in the ejaculate), during the study and in the 12 months following the last dose of study treatment. Men must furthermore refrain from sperm donation throughout the study until 12 months after the last administration of study treatment.

  10. In the opinion of the investigator, the participant must be able to comply with all study-related procedures, medication use and evaluations.
